Condition monitoring of engineering plants has increased in
importance as engineering processes have become increasingly
automated. However, electrical machinery usually receives attention
only at infrequent intervals when the plant or the electricity
generator is shut down. The economics of industry have been
changing, placing ever more emphasis on the importance of reliable
operation of the plants. Electronics and software in
instrumentation, computers, and digital signal processors have
improved our ability to analyse machinery online. Condition
monitoring is now being applied to a range of systems from
fault-tolerant drives of a few hundred watts to machinery of a few
hundred MW in major plants. This book covers a large range of
machines and their condition monitoring. This 3rd edition builds on
the 2nd edition through a major revision, update of chapters and a
comprehensive list of references & standards. Permanent magnet,
switched reluctance and other types of machines are now covered, as
well as variable speed drive machines and off-line techniques.
Contents cover an introduction to condition monitoring; rotating
electrical machines; electrical machine construction, operation and
failure modes; reliability of machines and typical failure rates;
signal processing and instrumentation requirements; on-line
temperature monitoring; on-line chemical monitoring; on-line
vibration monitoring; on-line current, flux and power monitoring;
on-line partial discharge (PD) electrical monitoring; on-line
variable speed drive machine monitoring; off-line monitoring;
condition-based maintenance and asset management; application of
artificial intelligence techniques to CM; and safety, training and
qualification.
Based on the spatial perspective, this book takes the urban area of
Xi'an, China, as the main research region and studies the balance
of resource allocation, focusing on educational resources and
school layout. The author constructs a mathematical model to
measure the level and types of resource allocation and regional
differences in primary schools, and uses GIS spatial analysis to
explore the efficiency and fairness of school spatial layout. The
book suggests a better way for the balanced development of basic
education in Xi'an city. It also provides theoretical foundations,
analytical methods and empirical support for the study of balanced
public resource management in public service, urban planning and
urban geography. This book is suitable for students and scholars of
tourism management, regional planning, facilities and urban
management, and those interested in resource allocation in Chinese
urban areas in general.
Offshore Wind Farms: Technologies, Design and Operation provides
the latest information on offshore wind energy, one of Europe's
most promising and quickly maturing industries, and a potentially
huge untapped renewable energy source which could contribute
significantly towards EU 20-20-20 renewable energy generation
targets. It has been estimated that by 2030 Europe could have 150GW
of offshore wind energy capacity, meeting 14% of our power demand.
Offshore Wind Farms: Technologies, Design and Operation provides a
comprehensive overview of the emerging technologies, design, and
operation of offshore wind farms. Part One introduces offshore wind
energy as well as offshore wind turbine siting with expert analysis
of economics, wind resources, and remote sensing technologies. The
second section provides an overview of offshore wind turbine
materials and design, while part three outlines the integration of
wind farms into power grids with insights to cabling and energy
storage. The final section of the book details the installation and
operation of offshore wind farms with chapters on condition
monitoring and health and safety, amongst others.
Condition monitoring of engineering plant has increased in
importance as engineering processes are automated and manpower is
reduced. However, electrical machinery receives attention only at
infrequent intervals when plant is shut down and the application of
protective relays to machines has also reduced operator
surveillance. A first edition of Condition Monitoring of Electrical
Machines, written by Tavner and Penman, was published in 1987. The
economics of industry have now changed, as a result of the
privatisation and deregulation of the energy industry, placing
emphasis on the importance of reliable operation of plant,
throughout the whole life cycle, regardless of first cost. The
availability of advanced electronics and software in powerful
instrumentation, computers, and digital signal processors (DSP) has
simplified our ability to instrument and analyse machinery. As a
result condition monitoring is now being applied to a wider range
of systems, from fault-tolerant drives of a few hundred watts in
the aerospace industry, to machinery of a few hundred megawatts in
major capital plant. In this new book the original authors have
been joined by Ran, an expert in power electronics and control, and
Sedding, an expert in the monitoring of electrical insulation
systems. Together the authors have revised and expanded the earlier
book, merging their own experience with that of machine analysts to
bring it up to date. The book is aimed at professional engineers in
the energy, process engineering and manufacturing industries, plus
research workers and students.
